4. For this series of 4 questions, two blocks, A and B, are connected using the cable and pulley system as shown. (The cable and pulley system is friction-less and weight- less.) The coefficient of kinetic friction between block A and the inclined plane is Hk = 0. 2. Initialy the blocks are moving but eventually come to stop. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 4) If block A weighs 120 lb and block B weighs 75 lb, and initially block A moves down the plane at a velocity of 6.9 ft/s, determine how far block A will move along the surface until it stops. Your answer must include 2 places after the decimal point and the proper unit. Take g = 32.2 ft/s². A C D B

if a hydraulic system has a cylinder containing fluid trapped between two pistons with equal diameters, how much force would the output (second) piston create if 25 joules of pressure were applied to the input (first) piston?
